Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A normal CLI launch can register and repeatedly beacon runtime metadata to a hard-coded private-address hub when Mnemo is enabled without its own URL. The behavior is automatic and not part of the install hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-07T10:17:21.700Z - **Finished:** 2026-09-07T10:19:16.000Z - **Download time:** 761 ms - **Static scan time:** 16716 ms - **AI review time:** 96819 ms - **Total time:** 114300 ms The recorded confidence comes from the underlying analysis.

The behavior is automatic and not part of the install hook. - **Trigger:** Run the blun or king command with an enabled Mnemo profile containing an agent name and no hub URL. - **Impact:** Discloses the host name, process ID, profile, package version, and agent identity to the hub. - **Evidence paths:** package.json, bin/launcher-runtime.js, bin/mnemo-connect-heartbeat.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T10:19:16.000Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic heartbeat to a hard-coded Mnemo hub. - **Attack narrative:** The package combines an automatic install hook with a runtime dependency on its own package name. More concretely, its launcher starts a Mnemo connection whenever a qualifying profile exists. A profile with an enabled Mnemo server and agent name but no endpoint silently uses http://100.85.21.103:7117. It immediately posts registration metadata containing the machine hostname and process ID, then repeats heartbeats every minute. This undisclosed hard-coded endpoint is not a package vendor endpoint and creates a concrete runtime metadata-exfiltration channel. - **Rationale:** The install hook itself is limited, but the executable contains an automatic hard-coded network beacon that discloses host metadata on normal use. The self-dependency adds supply-chain risk. - **Files touched:** package.json, scripts/fix-node-pty-perms.js, bin/launcher-runtime.js, bin/mnemo-connect-heartbeat.cjs - **Network endpoints:** http://100.85.21.103:7117 ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall hook and declares the package itself as a runtime dependency., Launching the CLI starts a recurring Mnemo heartbeat., When a profile enables Mnemo with an agent name but no hub URL, the code defaults to 100.85.21.103 and sends the host name, process ID, profile, and version there., The heartbeat begins immediately and repeats every minute without an explicit network consent step. - **Evidence against:** The inspected postinstall hook only changes permissions on node-pty spawn helpers., The observed beacon payload does not include file contents, environment variables, or credentials. ## Affected versions and remediation This report applies to blun-king-cli@9.1.519. - Avoid installing blun-king-cli@9.1.519. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
